Hey guys! I recently stumbled upon this website that has a bunch of videos called 'Cock Hero'.
It's basically like the game guitar hero, but for your cock!
Basically, you have to stroke to the beat of the sound or from the beat meter on the screen. If you don't like to do that, the video editing is actually really well done and these guys who make these videos defintely put a lot of time into it, so its defintely worth checking out!
